WebApr 1, 2024 · An underwater transmitter uses an acoustic speaker pointed upward to the surface. The transmitter sends sound signals, which travel as pressure waves. When these waves hit the surface, they cause tiny vibrations. Above the water, a radar continuously bounces a radio signal off the water surface. WebPenetration depth of radiowaves are however strongly dependant of the wavelength/ frequency spectrum of the transmitted wave. Submarine electromagnetic transmissions …
WebNov 12, 2013 · In order for someone underwater to hear you, the sound waves have to go from the air in your mouth into the water surrounding you. Sound waves have a hard time going from air into water and mostly get reflected at the air-water interface instead of being transmitted into the water.
